|---|
| Computed Tomography | extremely sensitive to differences in tissue densities, can use a radiopaque dye, allergy history important |
| Magnetic Resonance Imaging | imaging uses radiofrequency waves, produced without contrast dye or radiation, lies motionless for 15 to 90 minute, may need sedation |
| Positron Emission Tomography | uses radioactive substances, inhaled or injected, short lived radioactive substance, color coded images |
| Single Photon Emission Computed Tomography | able to provide brain's function, information about cerebral blood flow, will receive uses radioactive substances, check allergies |
| Lumbar Puncture | obtain samples of CSF, should be clear and odorless, explain will have discomfort |
| Contrast Studies | radiopaque dye injected, rapid sequence of radiographs taken |
| Electroencephalogram | records electrical impulses created by the brain, will not experience any shock during testing |
| Brain Scan | identifies tumors, hematomas in or around brain, radioactive material injected |
| Electromyography | studies changes in electrical potential in muscles and nerves, useful in determining neuromuscular disorders |
| Nerve Conduction Studies | electrodes applied to various nerve location on the skin, measure speed of electrical impulse travels along peripheral nerve |
| Echoencephalography | ultrasound of the structures of the brain, performed to detect intracranial bleeding or abnormalities in ventricles |
| Cranial Nerve I | Olfactory |
| Cranial Nerve II | Optic |
| Cranial Nerve III | Oculomotor |
| Cranial Nerve IV | Trochlear |
| Cranial Nerve V | Trigeminal |
| Cranial Nerve VI | Abducens |
| Cranial Nerve VII | Facial |
| Cranial Nerve VIII | Vestibulocochlear |
| Cranial Nerve IX | Glossopharyngeal |
| Cranial Nerve X | Vagus |
| Cranial Nerve XI | Spinal accessory |
